The AAVSOnet Epoch Photometry Database comprises robotically-processed photometry obtained from all images taken with AAVSOnet telescopes. The major component of this database are observations from the Bright Star Monitor network, as these telescopes have taken the majority of images. There are smaller datasets from telescopes that were only operational during the early days of AAVSOnet, covering fewer targets but going much deeper and often with high cadence (time series). For all current telescopes, the intent is to provide public access to older dat
